Depuis 100 ans, Magotteaux est un groupe de fonderies fournissant une large gamme de pièces d’usure pour les entreprises impliquées dans la fragmentation (mines, cimenteries, industrie du dragage, centrales à charbon et recyclage). Parmi ses différents business, l’entreprise Magotteaux est active dans le secteur du recyclage aux Etats-Unis et fournit aujourd’hui un tonnage attractif de 700 tonnes par an. Fière de cette success story, elle aimerait aujourd’hui s’intéresser au marché du recyclage des métaux en Europe.
Ce mémoire vise donc à étudier le potentiel du marché européen des shredders pour l’entreprise Magotteaux. Le shredder est une machine ou un broyeur utilisé dans le secteur du recyclage des métaux, pour laquelle Magotteaux est capable de fabriquer des pièces d’usure. Il s’agit donc d’un travail de recherche de type exploratoire et descriptif. Dans un premier temps, cette étude a pour objectif d’obtenir une représentation du marché européen du recyclage ainsi que de son potentiel, sa structure et ses enjeux. Ainsi nous verrons qu’aujourd’hui, avec plus de 110 millions de tonnes de ferrailles recyclées en Europe, le marché du recyclage a pris une place considérable dans notre économie. Avec des acteurs majeurs tels la France, l’Italie et l’Allemagne, l’Europe regroupe aujourd’hui plus de 300 installations de recyclage de type shredder et cela représente pour Magotteaux un potentiel équivalent à 5.000 tonnes par an de pièces d’usure.
Dans un second temps, l’objectif de cette étude est également de fournir à l’entreprise Magotteaux une vision claire du comportement de la clientèle étudiée. Ainsi, un échantillon de huit sites de recyclage fut étudié en France à travers une étude qualitative pour comprendre les craintes et attentes des recycleurs face à la maintenance de leur installation shredder. Nous verrons chez ces personnes que l’objectif est de recycler et broyer les déchets en vue d’en produire une matière primaire secondaire. Pour eux, les enjeux sont nombreux et le but est que leur broyeur produise de façon constante et à moindre coût un produit fini d’une qualité irréprochable. Pour cela, Magotteaux se doit à l’avenir d’apporter à ces recycleurs une gamme complète de pièces d’usure performantes mais aussi de les accompagner dans leur processus de broyage et de leur promettre une réactivité d’approvisionnement. Nous verrons également que pour pénétrer ce marché, Magotteaux se doit d’investir de son temps en proposant un monitoring pour la maintenance des installations ou encore des technologies innovantes...

Cette étude nous permet donc d’avoir une vision claire sur la structure actuelle du marché du recyclage en Europe et nous permet aussi de comprendre comment l’appréhender dans les prochaines années. For a 100 years, Magotteaux has been a group of foundries supplying a wide range of wear
parts for companies involved in fragmentation (mines, cement plants, dredging industry, coal
plants and recycling). Among its various businesses, Magotteaux has been active in the
recycling sector in the United States and currently supplies an attractive tonnage of 700 tonnes
per year. Proud of this success story, it would now like to look at the metal recycling market in
Europe.
This thesis therefore aims to study the potential of the European shredder market for the
Magotteaux company. The shredder is a machine or crusher used in the metal recycling sector,
for which Magotteaux is able to manufacture wear parts. This is therefore an exploratory and
descriptive research. Initially, this study aims to obtain a representation of the European
recycling market as well as its potential, structure and challenges. We will see that as of today,
with more than 110 million tonnes of scrap metal recycled in Europe, the recycling market has
taken a considerable place in our economy. With major players such as France, Italy and
Germany, Europe now has more than 300 shredder recycling facilities and it represents for
Magotteaux a potential equivalent to 5.000 tonnes per year of wear parts.
Secondly, the aim of this study is also to provide Magotteaux with a clear view of the behaviour
of the customers studied. Thus, a sample of eight recycling sites in France was studied through
a qualitative study to understand the pains and needs of the recyclers regarding the maintenance
of their shredder installation. We will see that the objective of these people is to recycle and
crush waste in order to produce a secondary primary material. For them, there are many issues
at stake and the aim is for their shredder to produce a consistent and cost-effective end product
of irreproachable quality. To achieve this, Magotteaux must in the future provide these recyclers
with a complete range of high-performance wear parts, but also support them in their shredding
process and guarantee them a reactive supply. We will also see that in order to penetrate this
market, Magotteaux must invest its time by offering monitoring for the maintenance of
installations or innovative technologies...
This study therefore gives us a clear view of the current structure of the recycling market in
Europe and also enables us to understand how to apprehend the market in the coming years.

The protection of human health and the environment (representing the main reason for waste management), as well as the sustainable use of natural resources, requires chemical, biological, physical and thermal treatment of wastes. This refers to the conditioning (e.g., drying, washing, comminution, rotting, stabilization, neutralization, agglomeration, homogenization), conversion (e.g., incineration, pyrolysis, gasification, dissolution, evaporation), and separation (classification, direct and indirect (i.e., sensor-based) sorting) of all types of wastes to follow the principles of the waste hierarchy (i.e., prevention (not addressed by this issue), preparation for re-use, recycling, other recovery, and disposal). Longstanding challenges include the increase of yield and purity of recyclable fractions and the sustainable removal or destruction of contaminants from the circular economy.This Special Issue on “Advanced Technology of Waste Treatment” of Processes collects high-quality research studies addressing challenges on the broad area of chemical, biological, physical and thermal treatment of wastes.

Environmental challenges posed by wrong end of lifeplastic management drive the plastics recycling schemes for energy recovery and cutting emissions, penalties, energy consumption, non-renewable resources, and manufacturing costs. Plastic recycling has the lowest environmental impact on global warming potential and total energy use. However, under-utilised plastic wastes due to low value issues with sorting/contamination pose major challenges. Novel technologies drive innovation in a circular economy model for plastics and employ reuse, recycling and responsible manufacture solutions, support the development of new industries and jobs, reduce emissions and increase efficient use of natural resources (including energy, water and materials). Many economies are working towards achieving a zero plastic waste economy. This Special Issue covers the applications of recycled plastics in the areas of energy recovery/alternative fuels, economic analyses, bitumen additives, flame retardants, recycled polymer nanocomposites to enhance the mechanical property, thermomechanical recycling to improve physical properties, mechano-chemical treatment, cryogenic waste tyre recycling, application in decarbonizing technology, e.g., cement industry, waste characterization, improving agricultural soil quality, as smart fertilizers. The Editors express their appreciation to all the contributors across the world in the development of this reprint. This reprint gives different perspectives and technical ideas for the transformation of plastic wastes into value-added products and to achieve higher recycling rates in the coming years.
